• The expression pedal of the B9.1ut is designed for operation with one foot. When the pedal is
fully turned to the right, pushing it strongly down, hitting it, or otherwise exerting strong force
on it will damage the pedal. Be sure to operate the pedal only within its designated range.
• If you loosen the pedal too much, the internal screw may come off, and you will no longer be
able to tighten the pedal. Perform this operation with care.
• If the screw should have come off inside the unit, contact your dealer or an authorized Zoom
service station.
• Never try to open the cabinet of the B9.1ut yourself, and never turn power to the B9.1ut on if
the screw is unsecured inside the unit. Otherwise the electronic circuitry may be seriously
damaged.
